# How can a reseller set up the SMS Sandbox for new users?

To configure sandbox parameters for new sign-ups:

1. In the **Set Feature** section, select **SMS Sandbox Configuration** from the dropdown.
2. Configure the following options:
   - **Allow Sandbox (SMS):** Toggle to **Yes** to enable sandbox.
   - **Default Credit/Wallet Amount:** Enter the initial test balance for new users.
   - **Set Default Sender ID:** Assign a default sender ID (must align with DLT template content for Indian users).
   - **Maximum Permissible Sandbox Mobile Numbers:** Define how many mobile numbers can be used for testing. Only whitelisted numbers will work.
   - **Whitelisting Mobile Numbers:** Choose between:
     - **Manual** – Add numbers directly yourself.
     - **SMS via OTP** – Allow users to add and verify their numbers via OTP.
3. Click **Save Changes** to apply the configuration.

This ensures that every new user signing up gets sandbox access with controlled credits, sender IDs, and testing numbers.
